I'm currently in the UK on a Tier 5 Temporary work visa (Government Authorised Exchange). My sponsor has indicated that they want me to stay an extra year but I'm having problems with visa options as the scheme they are under only allows my visa to be for a maximum of 12 months (ie it will expire this January). A Tier 2 work visa is not an option unfortunately, nor do I have British ancestry.
Can I return home (Australian passport holder), get another 12-month certificate of sponsorship from them, and re-apply for another Tier 5 GAE visa straight away? Or is there a minimum time I have to wait between work visas?
